I only use the free models on offer by duck.ai, and do it sparingly and in a self-contained manner. I decided that if those models are not enough for a problem, then I would probably be better off seeking a source with real authority and intelligence. They can track my anonymous private (network and browser) sessions all they want 😎, if they wish to.
(And that annoying non-cross-poster can go fuck itself. I'm deliberately posting this here because of it. So, Mission Accomplished!)
